An image stabilizing apparatus includes an optical element, a first fixing member, a movable member that holds the optical element, and is movably supported in a flat surface perpendicular to an optical axis, a ball sandwiched between the movable member and the first fixing member, a vibration wave actuator that includes a piezoelectric element and a vibrating plate, and moves the movable member, a slider that contacts the vibrating plate, and is provided in the movable member, a spring that pressurizes the vibrating plate against the slider, and a second fixing member fixed to the first fixing member so as to make the vibrating plate and the slider contact each other with a predetermined pressure.
Image shake correction device and imaging device
An image shake correction device includes a movement restrictor that restricts movement of a movable member in directions X, Y, θ, and Z. The movement restrictor includes a movement prevention member that is fixed to a base of a support member and prevents the movable member from moving in the direction Z while sandwiching the movable member in cooperation with the support member, a hole portion formed in the support member, and an insertion member that is formed in the movable member and is inserted into the hole portion. A wide width portion of the insertion member has a size that overlaps with the base of the support member even in a state in which an abutting portion of the insertion member is positioned in any position in the hole portion.
ACTUATOR, IMAGE CAPTURING UNIT AND ELECTRONIC DEVICE
An actuator is configured to drive an imaging lens system. The actuator includes a frame portion configured to accommodate the imaging lens system, a supporting portion disposed on the frame portion, a driving portion configured to drive the imaging lens system to move, an optical mark structure disposed on part of the frame portion, the supporting portion or the driving portion and a liquid disposed on the optical mark structure. The supporting portion is configured to support the imaging lens system and give the imaging lens system a degree of freedom of movement with respect to the frame portion. The optical mark structure includes a plurality of optical mark units arranged side by side. The liquid is in physical contact with the imaging lens system, the frame portion, the supporting portion or the driving portion that is adjacent to the optical mark structure.
